What is the best glue for joining two pieces of PVC trim? What is the best glue for bonding PVC trim to wood? How about metal?
Jun 22, 2018



We recommend PVC pipe glue with solvent for bonding the ends of PVC trim boards to themselves (Weld-On 705 by IPS, TrimTight by Trim Glue, Inc. or Christy’s Red Hot). Be sure the PVC pipe glue has sufficient working time to allow you to apply the glue and push the boards together before it cures.

If you are looking for more of a structural bond at shiplap or scarf joints, miter cuts (window surround), or for gluing sheets of PVC trim, we recommend PVC TrimWelder. For bonding to wood, we recommend Liquid Nails Sub-Floor .

Adhesive or Heavy Duty Construction Adhesive. For PVC trim to metal, PVC TrimWelder Adhesive works best.

There are three types of PVC TrimWelder Adhesives. Slow and Fast Cure for field joints and small glue-ups, and Laminating Grade for sheet glue-ups. Slow Cure should not be used at temperatures below 40°F. Remember to apply any adhesive to only one bonding surface, thus allowing the adhesive to penetrate into the cells on the other trim piece.
